RAILROAD-TIE.

Specification of Letters Patent.

Patented Oct. 30, 1.917.

Application filed August 10, 1917. Serial No. 185,565.

vide a novel form of railroad tie, having ribs so located as to recelve, engage and hold the ballast, thereby preventing thetie from shoving about on the road bed, or moving endwi-se.

In the drawings Figure 1 shows in top plan, a railroad tie constructed in accordance with the present invention;

Fig. 2 is a bottom plan of the tie;

Fig. 3 is a side elevation of the tie;

Fig. 4 is a longitudinal section of the tie;

Fig. 5 is a cross section on the line 55 of Fig. 1.

. In carrying out the invention there is provided a hollow metal tie 1 having'a flat upper face 2 provided with openings 3 adapted to receive rail holdin any desired kind. The tie 1 1s provided upon its bottom and upon its edges with spiral ribs 12 which converge, from the opmeans of posite sides of the tie, on the bottom of the tie, to define groups of V-shaped elements '14, extended inwardly from the ends of the tie, the apices of the V-shaped elements of the respective groups pointing toward each other, and the apices of all the V-shaped elements being located adjacent the longitudinal center of thetie.

Owing to the particular way in which the ribs 12 are formed, the tie will be held on the ballast against movement, and particularly against endwise movement.

Having thus described the invention, what is claimed is:

A railroad tie provided'upon its bottom and upon its edges with spiral ribs which converge, from the opposite sides of the tie,

on the bottom of the tie, to define groupsof V -shaped elements extended inwardly from the ends of the tie, the apices of the ribs of each group pointing toward the apices of the ribs of the other group.

In testimony that I claim the foregoing as my own, I have hereto aifixed my signature in the presence of two witnesses.

THEODORE I-I. KRUSE.
